ONE SIMPLE ANSWER FOR THIS: you must have a reason to do that.

You can't just stop smoking because one day you wake up and you say "oh i wanna stop smoking" there must be a reason for you to be motivated as fuck to stop a habit that you have developed. For me the only reason that I'm gonna stop smoking for is when I get diagnosed  with any disease or smth like that related to me smoking otherwise I wouldn't stop.

However there are many reasons why you should stop as it's time consuming, money consuming, health consuming and it has no benefits at all.
